Double integral with limits

Hey there everyone, I am having trouble solving a double integral using MATLAB.

The manual calculation is shown in the above figure. However, when i try to program it in MATLAB it is not displaying the correct ans as the given figure.

Th following code is displayed below.

f = @(x,y) exp(2*x).*(cos(y));

g1= @(x) sin(x);

q = integral2(f,0,pi,0,g1);

How do I troubleshoot this?

[madhan ravi]

 f = @(y, x) exp(2*x).*(cos(y)); % order of integration was wrong
g1= @(y) sin(y);
 q = integral2(f,0,pi,0,g1)
 % Using Symbolic Math Toolbox to verify
 syms x y
 q = int(int(exp(2*x).*(cos(y)), x, 0, sin(y)), y, 0, pi)
